18 inch wheels????
Ive been told that over time, 18 inch wheels can start to mess with the suspension geometry on 944's, and that I should go with 17's instead. I'm finding this hard to believe, anyway I just love the way 18's look on 944's. Can 18 inch wheels hurt the car in any way?

Porsche says no to 18s and the early (pre 89, IIRC) need a few parts upgraded for 17s. This comes up alot, and Danno had links to the important stuff a week or two ago. Either do a search, or just look through the last week or two worth of posts and you'll find it.

Seriously, you can fit 18s but you need to upgrade the A-arm caster mount at a minimum. There are plenty of 944s running around in Germany with TUV certification and 18" wheels. It can easily be done... no matter what Porsche says in their outdated TSB.

Hey Tarheel,
Here is the TSB.
It's your car but safety should be your primary concern, a nice looking car with the possibility of mechanical damage or being the cause of an accident kinda defeats the object dun it !

Installation of 18 Inch Wheels Not Approved By Porsche
Group - 4
Number - 9305
Model - All
Part Identifier - 4412
Subject: Installation of 18" Wheels Not Approved
April 15, 1993
ATTENTION: Service Manager/Service Technician
Models Affected: All
Concern: Retrofitting 18" wheels on Porsche vehicles which do not have 18" wheels as original equipment is NOT ALLOWED.
General Information:
Endurance tests have shown that equipping certain Porsche vehicles with 18" wheels in an application not already approved by Porsche Cars, N.A. may result in loosened bolts and/or threaded connections on the front wheel
carriers. This, in turn, may cause fractures in these components. Fractures
may also occur in the front strut mounts and in the body in the area of the
rear suspension as a result of the installation of 18" wheels not already
approved for installation for this specific application.
Such damage can occur without warning and the vehicle may become very hard
to control or steer as a result of this improper installation.
Porsche dealer personnel coming in contact with a vehicle that has been
retrofitted with 18" wheels in an application not approved by Porsche,
should inform the owner of the vehicle of the potential for damage to their
vehicle and loss of steering control. Porsche Cars, N.A. should also be
notified of any vehicles retrofitted with 18" wheels.
